pm-dispatch(decision-analysis): a decision analysis recommends exactly one option — retire the 「回退项」 line (the maintainer's word, 2026-10-19) #24444
Description
Filed by the director seat (summon #43 continuation 5, session_01QJC7i981TSs9L1CGJK59Ax) on the maintainer's words of 2026-10-19 in this seat's chat, after batch #368: 「你的决裁总是有一个回退合理吗？是完全不同的开发方向。最终结论应该只有一个吧？是 skills 的问题吗」, then 「同意」 on the change below. .claude/** is Tier S: the maintainer merges. ⛔ Not a claim.
Why
.claude/skills/pm-dispatch/references/decision-analysis.md asks every decision analysis for a fallback option: line 13 「推荐/回退/口径」 and line 30 「推荐 + 回退 + 置信缺口:荐一项、给回退项、明说看不见什么」. A fallback means something only when it is the same direction at a smaller scale or a later date, and line 32 already forbids recommending a staged half (「分期半量 ⛔ 不作推荐」). What the rule leaves is a second direction beside the first — on #24378 the seat recommended A with B′ 「as the fallback」, two different builds — which hands the decision back to the maintainer. The maintainer's rule: one recommendation; the other options are listed with why each is not taken; a confidence gap says what is unseen and never becomes a second recommendation.
What changes
references/decision-analysis.mdline 30: 「推荐 + 回退 + 置信缺口:荐一项、给回退项、明说看不见什么;⛔ 不沿用他席推荐。」 → 「推荐 + 置信缺口:只荐一项;其余选项各一句不取理由;看不见什么明说,⛔ 不因此给第二推荐;⛔ 不沿用他席推荐。」- line 13: 「推荐/回退/口径」 → 「推荐/口径」.
- Nothing else:
grep -rn "回退" .claude/skills/pm-dispatch/atorigin/mainfinds these two lines as the only decision-analysis uses; the other hits (shell fallbacks inplatform-readings.md, the rewrite 回退方式 indispatch-runbook.md, promote/回退 inreading-discipline.md, triage and os-dev wording) are untouched. The four facets, the 自检 line and the 裁后执行 paragraph stay as they are.
Acceptance
- The two lines read as above; no other line of the skill changes; the skill's own checks (the pm-dispatch skill lint, if
pnpm checkcovers.claude/) green; no changeset. - The PR stays a draft until the maintainer's hand merge (Tier S); it touches
.claude/skills/pm-dispatch/references/decision-analysis.mdonly.

Line 26 became 「- 推荐 + 置信缺口:只荐一,余各一句不取理由;盲区明说,⛔ 不因此另荐;⛔ 不沿用他席推荐。」 No other line changed and SKILL.md was not touched. The card's own line-26 text is 150 B against MAX_LINE_BYTES 120, and the file sits at its 50-line ceiling, so I took route A: compressed wording at 120 B with the line count unchanged. All five ruled clauses and the item name survive. The PR body has the clause-by-clause survival table. Route B (verbatim text over two lines, ceiling 50 to 51 under ruling record 6259199455) was not needed and was not taken. Premise check on f4755a6: the strings sit at lines 9 and 26, not 13 and 30. The git grep for 回退 over .claude/skills/pm-dispatch/ and .claude/agents/ gives 15 hits, and only these two are decision-analysis uses. No script, test or doc pins the old wording.
